Im using tdupe&tdumt&tduut configuration for adding cars. Maybe my problem with tduf is fixed at next update. I also tried on another computer, still didnt work. Most likely there is an issue with the game version, or it could be a java related issue.Thank you for your help

Lets try the debug thing. How to enable debug logs.
EDIT: Ok, i enabled debug mode. Database editor log is very long. I understood nothing from these text, you must be a very smart man djey. Thank you for helping me 
 

I even tried installing a new game and doing a clean setup, still gave the same error. Could it be a bug with the Windows 10 version?
I have an idea, can you send me your own database folder? It would be perfect if it works.
this is my database folder:

Sorry I've no clue. My last guess was you're using TDU Gold which is different from original dvd and was likely to cause issues. 
You may otherwise try with the command line tools to unpack database manually.

Hi,
have you tried opening database with TDU Modding Tools? TDUF uses same 'engine' to unpack BNK files.

Fair enough! That's how it feels like to have a life as well 😁

I still don't understand why it does not work although TDUF does modify the Colors.2dm file. I've no time to check in-depth right now.
Have you tested changing material colors with latest TDUF?

AFAIK you can't tune gear ratios on tuning packs, only apply coefs to basic physical parameters. If you wanna apply new gearbox settings, the only way to go is to use a dedicated vehicle slot in car physics data and set tuning to use this slot instead. You may always point to the same 3d models files etc. Platinum uses this trick a lot to change vehicle body for example.

That's an unknown issue, never happened before I guess. If there were errors, the DatabaseEditor logs would contain them... 
To see more logs, that may help: https://github.com/djey47/tduf/wiki/Settings#debugging
Something makes your database uncompatible with TDUF and it's hard to tell without any information. 
Otherwise with using TDUF in command line mode and try extracting database manually: https://github.com/djey47/tduf/wiki/Banks-CLI
TDUF FULL package is required to run as command line (from cmd.exe).

That is not related to windows 10 for sure, and my database is the exact copy of the one provided by TDU platinum. So you can get it from the latest update.
Best thing is definitely to enable debug logs in TDUF to know what's going on.
Ps: d3d9.dll file is not meant to be in this folder 

Hello Djey, I've been trying for days, but I couldn't read the database. No Java and framework issues. When I press load it says "Database could not be loaded". I tried both the original game and platinum, but its not working. Logs: Please help me
